Bring a pot of water to a simmer over medium-low heat.
Combine the egg yolks, sugar, lemon juice, and zest in a metal or glass heat-resistant bowl and whisk until smooth.
6 Egg Yolks, 1 Cup Sugar, 4 Lemons
Set the bowl over the simmering water, without letting the bottom touch, and continue to whisk.
Keep working-out that arm and whisk it vigorously for a good 10-15 minutes, until the curd has doubled in volume and is very thick and yellow. Don't let it boil.
Remove the bowl from heat and whisk in the butter, a couple of chunks at a time, until melted.
1/2 Cup Butter
Refrigerate until the custard is cold and firm.
Assemble The Trifle
Put the berries in a mixing bowl and toss them together so they are evenly distributed.
Fold the whipped cream into the chilled lemon curd to lighten it up into a mousse.
2 Cups Whipped Cream
Line a glass trifle bowl with pieces of pound cake to fit.
1 Pound Cake
Spoon a layer of the lemon curd over the cake, and then a layer of mixed berries.
Repeat the layers until the ingredients are used up, the last layer looks best if it's the berries.
Chill before serving.
Garnish with fresh mint.
Fresh Mint Leaves
Notes
*Just a little note, you HAVE to have simmering water and either a double boiler or a glass or metal bowl over a saucepan not touching the water in order for the lemon curd to double in size. *I always buy more berries because I like more than just a pint of each.refrigerate left overs
